Effectiveness of village health worker delivered smoking cessation counseling in Viet Nam

IntroductionnSmoking prevalence is high in Viet Nam, yet tobacco dependence treatment (TDT) is not widely available.nnnMethodsnWe conducted a quasi-experimental study that compared the effectiveness of health care provider advice and assistance (ARM 1) vs. ARM 1 plus village health worker (VHW) counseling (ARM 2) on abstinence at 6-month follow-up. This study was embedded in a larger two-arm cluster randomized controlled trial (RCT) conducted in 26 community health centers (CHCs) in Viet Nam. Subjects (N=1,318) were adult patients who visited any participating CHC during the parent RCT intervention period and were self-identified as current tobacco users (cigarettes and/or waterpipe).nnnResultsnAt 6-month follow-up, abstinences rates in ARM 2 were significantly higher than ARM 1 (25.7% vs. 10.5%; p<.001). In multivariate analyses smokers in ARM 2 were almost three times more likely to quit compared with those in ARM 1 (adjusted odds ratio [AOR]=2.96, 95% confidence interval [CI]=1.78-4.92). Compared to cigarette-only smokers, waterpipe-only smokers (AOR=0.4, 95% CI=0.26-0.62) and dual users (AOR=0.62, 95% CI=0.45-0.86) were less likely to achieve abstinence, however the addition of VHW counseling (ARM 2) was associated with higher quit rates compared with ARM 1 alone for all smoker types.nnnConclusionnA team approach in TDT programs that offers a referral system for health care providers to refer smokers to VHW-led cessation counseling is a promising and potentially scalable model for increasing access to evidence-based TDT and increasing quit rates in LMICs. TDT programs may need to adapt interventions to improve outcomes for waterpipe users.

Quality of Cardiovascular Disease Care in Small Urban Practices

PURPOSE We wanted to describe small, independent primary care practices’ performance in meeting the Million Hearts ABCSs (aspirin use, blood pressure control, cholesterol management, and smoking screening and counseling), as well as on a composite measure that captured the extent to which multiple clinical targets are achieved for patients with a history of arteriosclerotic cardiovascular disease (ASCVD). We also explored relationships between practice characteristics and ABCS measures. METHODS We conducted a cross-sectional, bivariate analysis using baseline data from 134 practices in New York City. ABCS data were extracted from practices’ electronic health records and aggregated to the site level. Practice characteristics were obtained from surveys of clinicians and staff at each practice. RESULTS The proportion of at-risk patients meeting clinical goals for each of the ABCS measures was 73.0% for aspirin use, 69.6% for blood pressure, 66.7% for cholesterol management, and 74.2% screened for smoking and counseled. For patients with a history of ASCVD, only 49% were meeting all ABC (aspirin use, blood pressure control, cholesterol management) targets (ie, composite measure). Solo practices were more likely to meet clinical guidelines for aspirin (risk ratio [RR] =1.17, P =.007) and composite (RR=1.29, P = .011) than practices with multiple clinicians. CONCLUSION Achieving targets for ABCS measures varied considerably across practices; however, small practices were meeting or exceeding Million Hearts goals (ie, 70% or greater). Practices were less likely to meet consistently clinical targets that apply to patients with a history of ASCVD risk factors. Greater emphasis is needed on providing support for small practices to address the complexity of managing patients with multiple risk factors for primary and secondary ASCVD.
